One of my shard in the index is in red state as the documents in that shard exceeded 2147483519 as below :

```auto
failed shard on node [GK1he55KSJmqQXx-qDrPFQ]: shard failure, reason [no-op origin[PRIMARY] seq#[350554097] failed at document level], failure IllegalArgumentException[number of documents in the index cannot exceed 2147483519]

```

according to prev posts the only solution is to reinde to new index with more shards or ILM in place  
while running re index on new index with 4 shards i get following error

```auto
{
    "error": {
        "root_cause": [],
        "type": "search_phase_execution_exception",
        "reason": "Partial shards failure (1 shards unavailable)",
        "phase": "query",
        "grouped": true,
        "failed_shards": []
    },
    "status": 503
}

```

dont understand how to proceed with re indexing

Can you share the output from `GET _cat/shards?v`?
